That last link appears dead at the moment.

+1 for using the term "Okey Dokey". =) Oh, and for tipping me off to sysadmin-network.com too. Never heard of that place before. Expect to see a certain goofy kitten amongst your ranks as soon as I can convince the administrator to accept my membership submission...

Sysadmin-network.com is an example, but it's community is small and comments are posted rarely. stadalone blogs are not what I wanted. I wanted social network of sysadmins|devs, where they can share their experience and get comments on it from others. Ex: planetsysadmin.com requires your own blog and readers leave a small amount of comments, thats not cool.

TiFFolk: Seriously, there aren't many resources for this. Sysadmin Network does have a relatively small user base, but it's also relatively new. Join and start a discussion. The more it gets advertised, the more people start using it. It's the kind of forum that you're looking for, I think. Have you tried IRC? #LOPSA is full of system administrators

if you want blog-type conversations, LiveJournal has several sysadmin communities
